The effects of high-intensity exercise on neural responses to images of food - The Weekly Essentials of Health from Usana Health Sciences

At a Glance

Research shows that high intensity exercise increases neural responses in reward-related regions of the brain in response to images of low-calorie foods and suppresses activation during the viewing of high-calorie foods.

Short bouts of intense exercise are known to suppress hunger through appetite regulating hormones. In a study published in the American Journal of Clinical Nutrition, researchers aimed to determine the effects of high-intensity exercise on central (brain) response to visual food stimuli.

The study included 15 healthy men of normal weight that completed two 60 minute trials: exercise (running at 70% maximum aerobic capacity) and a resting control trial. After each trial, images of high- and low- calorie foods were viewed and the brain response to the foods was measured using an MRI.

After the bout of exercise, thirst and core body temperature were increased while appetite response was significantly suppressed. Exercise significantly suppressed ghrelin (an appetite stimulating hormone) and enhanced the release of peptide YY (an appetite reducing hormone). When compared to the resting control, neural (brain) response in the brain’s reward related regions were stimulated in response to viewing the images of low-calorie foods but suppressed upon viewing images of high-calorie foods.

This study shows that high intensity exercise increases neural responses in reward-related regions of the brain in response to images of low-calorie foods and suppresses activation during the viewing of high-calorie foods. These central responses are associated with exercise-induced changes in peripheral signals related to appetite-regulation and hydration status.

About Me

Ekayani got her start in fashion at the center of all things "a la mode" in Paris, France in the late 80's. She walked the catwalk and worked the showroom for various houses and designers like YSL,Hanae Mori,Kansai Yamamoto,Elizabeth de Senneville,Loris Azzarro, Christian Dior and others with a special trip to Tokyo with Paco Rabanne. She has worked in Frankfurt,Berlin,Istanbul and New York. This began her on her path to empowerment by understanding that a woman's self belief is everything and that beauty comes in all shapes,sizes, colors and definitely from the inside out. She had access to all the "top" products on the market but found most of them to fall short of the promises to truly enhance well being.Her inspiration for good health comes from her family specifically her centenarian grandfather chef,author and healer Bernando LaPallo who impressed upon her from a very early age the benefits of good eating habits, exercise and a positive attitude.She is happy to be able to share with confidence products that have integrity that truly work. She is a "product of the products" and her testimony comes from a place of authenticity.
